. MACHINE FOR REDUCING BAGASSE T0 PULP TO EXTRACT THE SACCHARlNE MATTERTHEREFROM.

SPECIFICATION forming part of Letters PatentNo. 313,510, dated Iv/Iarch10, 1885.

Application filed May 15, 1851.

To all whom it may concern:

Beitknown that I, SIMON O. MEYER, a citizen of Paris, France, residingin the city and county ofPhiladelphia, State ofPennsylvania, havinginvented a new and useful ImprovementinMachincs for Reducing BagassetoPulp to Extract the Saccharine Matter Therefrom, of which thefollowing is a specification.

My invention has for its object the extrac tion of all the saccharinematter, or as large a percentage as possible, remaining in bagasse orcrushed sugar-cane. To accomplish this I reduce the bagasse to a finepulp or pomace,so as to break or open all the cells of the cane nototherwise affected by the cane-mill, to liberate the juice, and thensubmit the pulp to pressure to express the saccharine matter.

My invention consists of a series of cylindrical rasps, mountedpartially within an inclined chute, and provided with adjustable teethor cutters of coarse and fine pitch, for the reduction of the bagasse inrapid succession to as fine a pulp as may be desired. I attain theseobjects by the mechanism illustrated in the accompanying drawings, inwhich Figure 1 is a side elevation of the the entire machine. Fig. 2 isa half-elevation and halfsection on the line a b of Fig. 1. Fig. 8 is alongitudinal section through a portion of one of the cylindrical rasps.Fig. 4c is a transverse section on the line 0 d of Fig. 3. Figs. 5, 6,7, and 8 are edge views of the teeth or cutters detached from thecylinders, showing the different form of teeth employed. The cylindersA, A, and A are each flanged at the ends, as shown at B B, Fig. 3, andare provided with an annular rib, 0, arranged to form two divisionsaround the circumference. On each side of the said rib an annular grooveor channel, e, is formed for the reception of the inner ends of thetoothed or cutter bars D, which are placed in a longitudinal directionon the circumference of the cylinder with their outer ends restingagainst the flanges B and B.

E is a circular band, divided into as many segments as convenient foradjustment,placed over the ends of the toothed bars,and secured to theperiphery of the flanges B and B by means of the screws f f. The saidcylinders A, A, and A are mounted upon shafts F,

(No model.)

F, and F, which have their journals resting in bearings secured on thefront part of the housings G and G, as shown in Figs. 1 and 2. Thesehousings also form the sides of the inclined chute, and are arranged theproper distance apart to accommodate the cylinders, which projectpartially within the chute to act upon the descending bagasse.

H, H, and H Fig. 1,are inclined platforms, secured across'theintervening space between the sides of the chute and in the rear of eachcylinder, arranged to support the plungers I, I, and I", which press thematerial toward the cylinders.

The teeth on the bars D .of the cylinder A, Figs. 3 and 4, are of twodifferent shapes. The teeth g, viewed from the front or cutting edge,present a double-inclined or wedge shape, while the cutting-edges of thealternate teeth hare curved or rounded off at the apex and recede towardthe back part. presenting a cutting-edge somewhat in the form of aparabola. As this cylinder has the heaviest part of the work toperform,the teeth are necessarily made larger and stronger, so as toeffectually out through and mangle the bagasse.

The teeth ion the bars D of the cylinder A, Fig. 5, are of uniform shapeand size, being of a double incline or wedgeshap'e, and the teeth 70 onthe cylinder A are composed of curved or waved lines presentingacutting-edge semicircular in form. These two cylinders will reduce thebagasse toa fine pulp; but if a still finer pulp is desired, the machinemay be arranged to receive an additional cylinder or cylinders providedwith fine saw-teeth, as

shown in Fig. 7.

The toothed bars are arranged on the cylinders in two divisions, asabove stated, and are by this means readilyadjusted, the circular band Ebeing so divided into segments as to be readily removed and applied whenit becomes necessary to remove one or more of the bars for repairs. Thebars are also placed at intervals around the cylinders, with blocks ofwood L, Fig. 4,fitted in the intervening spaces, to hold themlongitudinally in position.

J, J, and J, Fig. 1, are nozzles for introducing jets of water into themass of pulp for the purpose of retaining the same in a semifluid state,so as to be more readily worked.

Brushes K, K, and K Figs. 1 and 2, with their ends secured to sideprojections, V V, are arranged across the housings in front of a and incontact with the teeth of each cylinder,

for the purpose of removing any particles of pulp which might adhere tothe teeth and interfere with their proper action. The bagasse to beacted upon is received at the upper part of the chute from an endlessapron or canecarrier,and falls upon the inclined plate M, and in passingdownward is acted upon by the first cylinder, which reduces it tothreads or filaments before it passes to the second cylinder, where itis reduced to a finer degree, and then on to the third cylinder, whereit is reduced still finer and the rasping process completed, from whencethe pulp passes to a suitable receptacle or directly into the press.

The entire machine is placed near the canemill, and the bagasse issubmitted to the rasping process just as it comes from the mill; but itmay be necessary to reduce it to short pieces before it passes into themachine, and for'this purpose I propose to use a circular saw orrevolving cutter to cut the bagasse into short sections.

The axles of the cylinders A, A, and A are provided with pulleys N, N,and N, which receive motion communicated by belts from shafting andpulleys driven by the engine of the cane-mill or independent power.

The plunger-s I, I, and 1, Figs. 1 and 2, which are reciprocated uponthe inclined platforms H, H, and H to carry the bagasse or pulp towardthe rasping-cylinders, are operated by means of grooved heart-shapedcams 0 0 and pivoted levers P P. The said cams are placed in pairs uponshafts R, R, and R, and receive motion from spur-wheels S, S, and S andpinions T T. i

I do not wish to limit myself to the exact construction of the machineas described, as it is obvious that many changes may be made withoutdeparting from the spirit of my invention.

What I claim as my invention, and desire to secure by Letters Patent, is

1. In a machine or-apparatus for reducing bagasse to a fine pulp orpomace, the combination of the cylinders A, A, and A toothed bars D, D,and D wooden block L, and segmental bands E, substantially as shown anddescribed.

2. The combination of the cylinders A, A, and A provided with theflanges B B, rib C, and teeth 9, h, i, and is, substantially as and forthe purpose shown and described.

3. The combination of the cylinders A, A, and A housings G and G,inclined platforms H, H, and H plungers I, I, and I, waterjets J, J, andJ", and brushes K, K, and K, substantially as and for the purpose shownand described.

4. The combination of the cylinders A, A, and A shafts F, F, and Fpulleys N, N, and N", housings G and G, plungers I, I, and I, shafts R,R, and R, heart-cams O 0, 1evers P P, spur-wheels S, S, and S", andpinions T T, substantially as shown and described.
